Earlier this year, Microsoft had announced that Windows 10 was powering over 500 million devices. After over six months now, the company has offered a second update on how fast the operating system is being adopted. According to the company’s CEO, Satya Nadella, over 600 million active devices are now running Windows 10.

While it’s just a 100 million more devices, the growth rate appears to be going steady when compared to September 2016’s announcement that was followed by another 100 million users in May, this year. The growth had, however, significantly stalled after the initial bump once the company stopped offering the operating system as a free upgrade to Windows 7, 8 and 8.1 devices in 2016. The free upgrade offer still works, however, it is more of a workaround when compared to aggressive upgrade notifications that were sent to compatible Windows machines following the release of Windows 10.

Nadella shared the latest statistics at the company’s annual shareholders meeting today and this figure includes all the Windows 10 machines, including PCs, Xbox One consoles, Surface Hub, tablets, and phones.

Microsoft had initially hoped to get over 1 billion devices on Windows 10 within two to three years of its release in 2015

The company had high hopes of reaching to over 1 billion devices in two to three years after the initial public release of Windows 10 in 2015. However, that figure is no longer mentioned by the Redmond software maker as enterprises and users still weigh their choices between the trusted old Windows 7 and the new Windows as a Service model.

However, once on Windows 10, Microsoft will no longer have to worry about the adoption rate thanks to the same WaaS strategy. So far, the company has managed to upgrade almost all of the Windows 10 early adopters to more recent versions of Windows 10. The latest Windows 10 Fall Creators Update, for example, has already been installed by over 20% of all Windows 10 users just over a month after its rollout.
